Unvented Operation
When using an unvented configuration
(agricultural use only)
, consider the following:
• A factory supplied vent cap/diffuser (P/N: WVE-GALV)
must
be used.
• Where unvented heaters are used, natural or mechanical means
must
be provided to supply
adequate ventilation - a minimum of 4 cfm/1000 BTU/h (0.38 m
3
/kW) input of installed heaters.
NOTE:
Gravity or mechanical means may be used to accomplish the air displacement. Local
codes may require that the mechanical exhaust system be interlocked with the electrical supply
line to the heaters, enabling both to function simultaneously.
• Exhaust openings for removing the flue products must be located above the level of the
heater(s).
WARNING
!
Not for residential use
. The use of unvented tube heaters in residential indoor spaces
may result in property damage, serious injury or death. Use unvented operation in
commercial and industrial installations with proper ventilation rates only.
